I'll first insert my whole splunk search query and show whats it showing and whats the expected result

It gives me this table but as I cant show all the tables row ill show the relevant ones 

abc 1235976165192024/06/15 09:22:372024/06/15 09:24:162024/06/15 09:24:169902024/06/15 09:24:2610910

abc 219597614935        



just assume the booking_timestamp, booking_mq_timestamp, booking_ep_timestamp, mq_latency, ep_latency are all filled

Ok but since my catchup_updated_time is taking from a log entry its populated (eg. 2024-06-15 10:57:03,114 [Www] - Done incremental update. Max SSSSSS TradeID: 597618769), but the rest of the rows/columns are not populated.

I want to highlight this specific row since its taking from logs and also fill the empty catchup_updated_time such that 597616518 and 597616517 should take the catchup_updated_time, latency etc of 597616519 as their id is before and 597616519 is the max id taken from logs its row should be highlighted. hence anything before or smaller than 597616519 should have same catchup_updated_time. However not until 597614937 as it already has a catchup_updated_time taken from logs. So same for the rest of the rows. Is this complicateD?

Please let me know if you need more info

Your question would be much easier to understand if you skip the complex SPL, first give sample data (anonymize as needed), illustrate desired output, then explain the logic between illustrated data sample and desired output without SPL.  To diagnose your attempted SPL, you also illustrate the actual output from that SPL, and explain how actual output is different from desired output if that is not painfully obvious. (Remember: What is "obvious" to you is not always obvious to volunteers who lack intimate knowledge about your dataset and your use case.)

As a side note, the illustrated SPL implies that your sourcetype=sss_trade_www_timestamp contains snippets like "trade_id=foo",  "mx_status=bar", and so on.  If so, Splunk would have extracted trade_id, status, etc. without your rex.  Is there any reason Splunk is not giving you those?

ah okay thanks gotcha. 

Current output is like the table i shown and desired output is the table after that.

catchup_updated_time is not populated for some as its taken from another sourcetype which is www_cattchup_Logs

Please let me know if futher info is required

Will filldown do the trick? E.g.

| filldown catchup_updated_time
